Thus, furthermore, is overcome 65 15 ing one application of the device to meters the chief disadvantage in devices of this kind employing the diskfaction, and Fig. 2 an enas heretofore designed, in that the slight area lm'ged detail View here exposed to the full internal pressure,

The construction of the device in detail is that only of the spindle, is such as to not maas follows: A casing 3 of any suitable conteriallyaffect the uniformity or sensit-iveness 7o 2e struction (the casing of a Water-meter being of the action between wide ranges of pressshown) is formed in part with or is adapted ure. In actions of this type there is a tend to receive a threaded plug 2. There the plug ency less or greater, depending upon the is separate from the casing there is a gasket frictional resistance or work being done, to 5 insuring a joint. At the inner end of the revolve the spindle tending' to loosen it in the 75 2 5 plug is a spherical socket (5 to Which the balltip, &c. This is here avoided by forming a segment 7 of a spindle 8 is adapted. The slot 17 in the segmental ball, to which a pin center from Which the ball and socket are 18 fast in the Washer or the socket is freely developed is at 9. A thin but rigid conical adapted. In this Wise anytendency to rotate Washer lO is applied perforated at its apex to is resisted by the Walls of the slotl and pin, 8o 30 a slightly-greater diameter than that of the although the spindle is perfectly free to be spindle, and flanged, as at ll,which ange is gyrated. adapted to a bearing 12 on the plug.

So, too, the rubber tip may be otherwise formed, as indicated by dotted lines 25. It willalso be observed that the device when used in connection With a disk-action also acts as a means of control for the disk, the tension of the tip, the contact of the conical roller and of the lower surface of the ball-segment upon the Washer all tending to maintain the disk in proper contact with the trustums of the disk-chamber Casin g.

Without limiting ourselves tothe precise construction shown, we claiml. The combination, with the plug and spindle having a segmental ball-andfsocket bearing, ot the internal Washer inclosed by an elastic or yielding tip secured to thc plug and to the spindle, for the purpose specified.

2. The elastic or yielding tip and rigid Washer inclosed thereby, in combination with the ball-and-socket bearing, the spindle, and the plug, substantially as described.

3. The combination, with a spindle adapted to be gyrated to transmit rotary motion, of a spherical elastic or yielding tip fast to the spindle and to the mountingthereof, substantially as specified.

4V. The combi1.iation,\rith the elastic or yelding ti p, spindle, and ball and socket properly mounted, of the Washer having the perforation for the spindle coincident with the center of motion of the said ball and socket, substantially as specified.

5. The combination,\vith the elastic or lyielding tip, spindle, and ball and socket properly mounted, of the conical Washer, substantially as specified.

(i. The c0mbinatiou,with the elastic or yielding tip, washer, spindle, and ball and socket properly mounted, of the slot and pin, iior the purpose specified.

7. The combination of the spindle and elastic tip properly mounted, adapted to be gy* rated totransmit rotary motion With the driving-arm having a ilarin g slot, substantially' as shown and described. i

In testimony whereof We have signed our name to this specification in the presence of two snbscribin g witnesses.
